COMBINED AERATOR AND DIPPER.

SPECIFICATION forming part of Letters Patent No. 687,635, dated November26, 1901.

Application filed March 8, 1901.

To an whom it may concern.-

Beit known that I, DAVID DANIEL KIMBER- LIN, a citizen of the UnitedStates, residing at Hudson, in the county of Summit and State of Ohio,have invented anew and useful Gombined Aerator and Dipper, of which thefollowing is a specification.

The present invention relates to a combined milk aerator and dipper, andparticularly to that type covered broadly by a previous patent issued tome on August 7, 1900, and numbered 655,245. In said patent aconstruction is shown and described embodying a handle and a cup pivotedat its upper edge to the handle. This cup is adaptedto'be arranged withthe open end down and plunged to the bottom of a can of milk, afterwhich it is inverted to release the air contained therein which bubblesup through the milk. There are certain objections to this construction.In the first place, because of the cup being pivoted at itsupper edge,stops are necessary to prevent the complete inversion of the cup, sothat when it is drawn from the milk it will not be filled; but even withthese stops it will not readily reassume its proper position to carrythe air into the milk after its withdrawal therefrom'when it is desiredto repeat the operation, and it therefore becomes necessary to hold it,either by hand or against the wall of the can, until its mouth has beenforced below the surface. A further objection appears when the device isused as a cup, for the reason that because of the stops milk cannotreadily be dipped from a can, and, again, because of the free movementof the cup the contents are veryeasily spilled.

The present invention aims to improve this construction and overcome allof the above objections by providing a device in which the cup willautomatically assume its proper position to carry air into the liquidand also by providing means whereby the cup and handle may be lockedagainst relative movement, so that the device may be used as a dipper.

To the accomplishment of these objects the construction shown in theaccompanying drawings and described in the following specification ispreferred; but it will be understood that this construction may bechanged and modified,if desired, provided such change Serial No. 50,352.(No model.)

view similar to Fig. 3, butillustrating the position and relation of thecup after the air has escaped therefrom. Fig. 5 is a detail longitudinalsection of a portion of the cup and handle locked against relativemovement. Fig. 6 is a detail view of the pivotal connection.

Similar numerals of reference designate corresponding parts in all thefigures of the drawings.

Broadly the construction comprises, as in the above-described patent,two members-a handle 10, to one end of which is pivotally connected acup 11. The handle 10 prefererably comprises a pair of spaced parallelarms 12, formed by bending a wire or rod upon itself. These arms areoffset atone end, as at 13, to form an abutment 14, and their ends arebent outwardly to form a pair of oppositely-disposed pintles 15.Connecting the arms 12 intermediate their ends is a metallic strip 16,having a slot 17, in which is slidably mounted a latch 18. A pair oflugs 19 are arranged upon the handle contiguous to the lower end of theslot. The latch 18 comprises a shank 20, which passes through the slot17 and has on one side a pair of oppositely-disposed arms 21 and 22,arranged longitudinally of the handle, the opposite end beingprovidedwith a transverse retainingpin 23, that is adapted to drop below theholding-studs 19 when the latch is in its lowest position.

The cup 11 is preferably constructed in the usual form, havingcylindrical side walls 24, a closed bottom 25, and an open top 26,having an outstanding bead 27 about its edge. Arranged upon its sidewalls and contiguous to the bottom or closed end is the hinge-ear 28.This is preferably in the form of a loop having side arms 29, the freeends of which are .bent to provide a pair of spaced hingeeyes 30. Theloop is secured flat upon the 'narily proved sufficient.

wall of the cup with the connecting portion 29 between the two side armsarranged at the edge of the same. The eyes 30 will thus be locatedintermediate the ends of the cup, but contiguous to its lower edge. Inassembled relation the pintles 15 of the arm are sprung into the eyes30, whereby thecup and handle are pivotally connected. The cup is thusfree to swing completely about the end of the handle, and the connectingportion 29 of the hinge-ear is arranged to rest against the shoulder orabutment 14 of the handle when the cup is in its inverted position. Itwill therefore be maintained at an angle to the handle. On the otherhand, when the cup is swung against the opposite side of the handle orin its upright position its upper edge is arranged contiguous to thelatch 18, and the locking-arm 21 can be slipped over the same.

The manner of operating the device is substantially as follows: Inaerating milk the cup is left free to swing, and it will thereforeassume an inverted position, because of the pivot being near the bottomor closed end.

The handle is then held in upright position against one edge of themouth of the can, and the cup is plunged to the diagonally oppositeportion of the bottom thereof. The

cup will be held in its inverted position by the upward pressure of theimprisoned air and at the same time will be practically vertical, asshown in full lines in Fig. 3. The upper end of the handle is then movedto the opposite side of the can-mouth, thus slightly tilting the cup andpermitting some of the confined air to escape, after whichthe upper endof the handle is held against thislatter side and the cup is movedacross to the opposite side. It will therefore be gradually tilted moreand more until it assumes the position shown in dotted lines in Fig. 3,and the air will have been distributed across the entire width of thecan. To complete the operation and empty the cup of air, a slightdownward pressure is applied to the handle, which will move the cup to ahorizontal position, as shown in Fig. 4. Upon raising the cup it willimmediately reassume its inverted position, so that when withdrawn fromthe liquid it will be emptied of the milk and be in proper position tobe againinserted. This operation is repeated a sufficient number of 3times to completely aerate the milk. By experience a period of twominutes has ordi- In using the device as a dipper the cup is arrangedagainst the handle with its open end uppermost. The latch is thenengaged over the edge, thus holding the cup and handle against rolativemovement. In this position the retainingpin 23 will be seated behind theshoulders or studs 19-, and thus the latch will be securely held againstaccidental displacement. It will be observed that when in this positionthe bead at the upper edge of the cup abuts against the handle, and thuscompensates to a certain It will thus be seen that the presentconstruction has several important advantages in that when in use as anaerator it will always assume its operative position and willautomatically be emptied of the liquid when withdrawn therefrom.Furthermore, it is capable of use as an ordinary dipper which can beused to withdraw milk or other liquid from a can having a narrow mouth.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a device of theclass described, the combination with a handlemember, of a cup member pivoted to the handle member, and adapted to bearranged with its open end up,- and coacting means carried by the handleand cup members to hold the cup member with its open end up, said handlemember having a portion located in the path of movement of the cupmember to maintain the same open end down while being plunged into abody of liquid.
